The development of service-based software and web-based application aims for providing user-demand service. On-demand software is emerging for same reason. Software delivery models like on-demand software is expected to change the software industry as an important technical revolution with the firm's strategy. Few research, however, has been done on the on-demand software. While much research on ASP and SaaS focused on firm' use, this study intends to examine the intention of using on-demand software targeting personal user. The intention to use of on-demand software was empirically examined in terms of quality, user characteristics, usefulness, easy of use, and security. Results shows that usefulness and easy of use are most significantly related to the intention of using on-demand software. Other factors are also found to affect the intention to use of on-demand software. This study contributes to improve the understanding and interest in on-demand software and it is expected to spread widely for individual user.

On-Demand services have emerged as one of the core business strategies for delivering new experiential values by providing customized services in different user-needs nowadays. Based on the Stimulus-Organism-Response (S-O-R) framework, this paper focuses on the factors of environmental stimulation and emotional states of the demand-side that induce continuous intention of use from the On-Demand services. The study defines 'Informativeness', 'Fulfillment', 'Trust', and 'Convenience' as the properties of the On-Demand services and considers 'Playfulness', 'Customer Return on Investment (CROI)', and 'Service Excellence' as the aspects of the experiential values. The research shows that 'Fulfillment', 'Trust' and 'Convenience' affected the experiential value in 'Kakao Taxi (On-Demand transportation service)' while 'Informativeness', 'Fulfillment', 'Trust of platform', and 'Convenience' are represented as the related factors to the experiential value in 'Baedal Minjok (On-Demand food delivery service)'. The experiential value factors, 'CROI' and 'Service Excellence', are shown directly related to the continuous intention of use in both services. A partial mediation relationship is, furthermore, observed between the aspects of 'CROI' and 'Service Excellence' in Kakao Taxi and its 'Convenience' and 'Continuous intention of use.' In Baedal Minjok, a partial mediation relationship is found between the 'CROI' with its aspects of 'Trust of the platform', 'Convenience', and 'Continuous intention of use' as well. The results of this study may contribute a comprehensive understanding of the purpose of On-Demand services and its needs from the demand-side thus can be helpful for the supply-side.

On the basis of the concept retained in nutition label(NL) the consumer's perception use and demand on NL nutrition knowledge(NH) purchase of nutrient controlled food and dietary modification for health were examined. The subjects were 1203 house wives mainly in the age of 30-40 and self administered questionnaire was employed. The results were as follows. Subjects' demand on nutrition information was greater while the availablity and usefulness of NL was unsatisfactory. The purchase frequencies of nutrient controlled foods were higher compared to NL reading. The use comprehenison reliability of nutrition information were better in high NK group compared to low NK group except the reliability on health claims. The required nutrients for content information were in the order of calorie Ca cholesterol Fe protein and total fat. The demand for nutrient content information was carrelated with intention of subjects' dietary modification but not the use of NL. These results indicate that NL be a good source of nutrition information and the consumers' demand for NL was based on their dietary purpose though the use of NL was unconfirmed.

This study was performed to improve water demand estimation and analize correlation between generation of domestic sewage and domestic water use. To improve the prediction of water demand estimation, new water demand equation was developed. The results is as follows. $InQ_t = {\beta}_0+{\beta}_1InP_t+{\beta}_2InY_t+{\beta}_3InH_t+{varepsilon}_t$By using the statistical analysis of the "generation of domestic sewage" and "domestic water use", the regression equation between them is formed. The result is as follows. Generation of domestic sewage : 0.8487 $\times$ Domestic water use + 684.57 ($R^2$= 0.972)>$R^2$= 0.972)

Purpose : This study was to analyze the demand for emergency ambulance service and to characterize the factors associated with the demand. Method : The basis for the model was from the actual demand for public emergency ambulance and socioeconomic and geographic characteristics. Multiple regression analyses were done for the related characteristics of public ambulance service. Result : The model explained total demand with a high degree of accuracy : the coefficient of determination($R^2=0.96$). For the regression, the set of variables indicative of low socioeconomic status were all significant. It showed the inappropriate use of public ambulance system. Public ambulance demand increased in higher housing density, low income, male unemployment and female labor force. Conclusion : The demand for public ambulances appeared to be highly predictable, using a simple linear model employing socioeconomic variables, quality of service variables, and land use variables. Low-income families tended, to use the public ambulance system more often than higher income. Area having elderly people or children also made many calls. Estimated demand calls were stable and had a tendency to be similar incident types.

The rail passenger demand for the railroad operations required a short-term demand rather than a long-term demand. The rail passenger demand can be classified according to the purpose. First, the rail passenger demand will be use to the restructure of line planning on the current operating line. Second, the rail passenger demand will be use to the line planning on the new line and purchasing the train vehicles. The objective of study is to analyze the travel behavior of rail passenger for modeling of short-term demand forecasting. The scope of research is the passenger of KTX. The travel behavior was analyzed the daily trips, origin/destination trips for KTX passenger using the ANOVA and the clustering analysis. The results of analysis provide the directions of the short-term demand forecasting model.

지역단위 수요를 분석할 수 있는 자료상의 요건은 수요량에 관한 것이다. 분석하고자 하는 지역의 수요량을 파악해야 수요를 분석할 수 있는데, 현실적으로 모든 수요량을 파악한다는 것은 곤란하다. 이러한 이유로 대부분의 지역단위 수요량 조사는 광석수요량, 금속괴 수요량 등 특정 단계의 거래량을 이용하게 된다. 그러나 이는 수입된 최종제품의 부분품으로서 금속자원 수요량이나 다른 단계의 제품으로 수입된 수요량은 고려하지 않은 해당 금속자원의 수요량 중 일부분에 해당되는 것이다. 이와 같은 자료상의 한계를 인식하여, 본 연구는 국내 금속괴의 수요를 분석함에 있어 개념적으로 이분하여 국내사용을 목적으로 하는 수요와 국외사용을 목적으로 하는 수요로 구분하였다. 국내사용을 목적으로 하는 수요는 국내의 경제, 기술 등 요인에 따라, 그리고 국외사용을 목적으로 하는 수요는 국외 소득변화가 우리 경제에 영향을 주는 정도에 따라 변화하는 양상을 보일 것이다. 이를 근거로 사용강도(intensity of use)의 가설을 도입하여 국내 동괴, 연괴, 아연괴의 수요를 모형화하고 실증분석하였으며 유의한 결과를 도출했다.

본 연구는 시스템 다이내믹스 기법을 활용하여 성남시의 토지이용수요를 예측하고 가족구조 변화와 토지이용밀도 조정정책이 토지이용수요에 미치는 영향을 모의실험하는데 연구의 목적이 있다. 이를 위해 분석모형을 설계하고 시뮬레이션 결과를 통해 시간의 흐름에 따른 토지이용수요의 변화를 살펴보았다. 분석결과에 의하면, 2035년 기준으로 주거용지는 2.08km², 상업용지는 1.36km²의 추가 공급이 필요하고, 공업용지는 현재 공급면적으로 수요를 충족할 수 있는 것으로 나타났다. 한편, 기본 모형에서 변수값을 변경하여 세가지 정책실험을 실시하였다. 첫 번째 정책실험에서는 가구원수가 기본 모형에 비해 급격히 감소할 경우에는 주거용지가 최대 7.99km² 추가공급이 필요한 것으로 나타났다. 두 번째 정책실험에서는 아파트 용적율이 200%에서 300%로 상향하면 현재의 성남시 주거지역 공급면적으로 주거용지 수요 충족이 가능하였다. 세 번째 정책실험에서는 상업지역 평균층수를 4층에서 5층 상향하고 상업지역 건폐율을 80%에서 85%로 상향하더라도 상업용지의 수요가 성남시 상업지역 공급면적을 초과하는 것으로 나타났다. 본 연구는 시스템 다이내믹스를 활용하여 토지이용수요 예측의 새로운 분석모형을 제시하고, 성남시의 실제 도시계획 현황 및 통계치를 적용하여 모형을 실증하였다는데 연구의 의의가 있다. 향후 성남시 토지이용수요 예측 및 분석 모형의 정교화를 위한 후속연구가 이루어져야 할 것이다.
